CHURN.

Specification of Letters Patent.

Patented Aug. 15, 1905;

Application filed November 3, 1904. Serial No. 231,221.

To all whom, it may concern:

Be it known that I, CHARLES H. SHIPPLETT, a citizen of the United States, residing at Hermon, in the county of Knox and State of Illinois, have invented'a new and useful Churn, of which the following is a` specification.

This invention relates to churns, and has for its object to improve the construction and increase the elficiency of devices of this character. Y

With these and other objects in view, which will appear as the nature of the invention is better understood, the same consists in certain novel features of construction, as hereinafter fully described and claimed.

ln the accompanying drawings, forming a part of this speciication,and in which corresponding parts are denoted by like designating characters, is illustrated the preferred form of the embodiment of the invention capable of carrying the same into practical operation, it being understood that the invention is not necessarily limited thereto, as various changes in the shape, proportions, and general assemblage of the parts may be resorted to without departing from the plinciple of the invention or sacrificing any of its advantages.

In the drawings thus employed, Figure 1 is a sectional front elevation. Fig. 2 is a side elevation of the upper portion of tbe improved device. Fig. 3 is a plan view of the creamreceptacle with the frame of the dasher-operatingmechanism in transverse section on the line 3 3 of Fig. 1.

The improved churn comprises a cream-receptacle 1() of any size orform, but preferably square and formed of sheet metal, such as galvanized iron or tin, with a metal frame 11 supporting the bottom end and serving as a band around the same, and also provided with projecting lugs 12 13 for the feet of the operator to steady the device while operating the dasher mechanism, as hereinafter shown, a binding -frame 14 embracing theI upper edge and projecting inwardly thereover and secured as by rivets 15, the upper frame having a loop 16 on one side and a hook 17 on the other side.

Resting upon the frame 14 is a standard or` frame 18, having a hook 19 upon one side for detachably engaging the loop 16 and a stud 2O on the other side for engagement by the hook 17, the hook being secured from accidental displacement by a stop-pawl 21. The

lower portion of the frame 18 is broadened laterally into feet 22 23 to provide the requisite stability and converges at the upper part and provided with bearings 24 25 for supporting shafts 26 27 for rotation, the shafts disposed at right angles and provided, respectively, with gear-pinion 28 and gear-wheel 29, they lower end of the shaft 26 extending below the bearing 24 and formed square, as at 39. The shaft 27 is provided with operating-cranks 30 31 upon its ends extending in opposite directions, so that both hands can be employed in operating the churn. Mounted for rotation in the receptacle 10 is a dasher-shaft 32, stepped by the lower end, as at 33, and with the upper end extended abovei the upper line of the cream-receptacle and having a sleeve 34 slidable upon the extended end. The sleeve is provided with oppositely-disposed longitudinal slots 35 36, through which a transverse pin 37 in the shaft 32 projects, so that while the sleeve is free to move longitudinally of the shaft a distance equal to the length of the slots it will be rotated or oscillated with the shaft, as will be obvious. The upper end of the sleeve converges and terminates in a socket 38 for engaging the square end 39 of the shaft 26 and with a spring 40 between the upper end of the shaft 32 and the shoulder formed by the converging portion of sleeve.

The dasher member of the device consists of a plurality of radiating arms 41, preferably circular in transverse section and arranged in spiral order, as shown, so that they will move the cream vertically of the receptacle at the same time that they rotate it, and by reversing the motion the cream may be caused to move in either direction.

The receptacle is provided with a detachable cover formed in two parts 42 43 with lifting-knobs 44 45 and resting upon the upper rim-frame 14, the cover members p rovided with depending ribs 46 47 to retain them in`position and prevent lateral movement. The cover members are provided with recesses for fitting around the shaft 32 from opposite sides just beneath the lower end of the sleeve 34, andthus form stops to prevent the downward movement of the latter when the cover members are in position. By this means the cover members perform the two- `fold function of means for closing the creamreceptacle and also as stops to prevent the vertical action of the spring-supported sleeve while the closure is in operative position. Thus no danger exists of the accidental release of the sleeve and the dasher-shaft supported thereby during the rapid action of the mechanism, no matter'how severe the jarring and concussion. may be.

With a churn thus constructed the operation is as follows: The cover members having been removed and the cream inserted in the receptacle, the dasher-shaft 32 is set upon its l step 33 and the sleeve 34 compressed until its socket 38 snaps over the square end 39 of the shaft 27 The cover members 42 43 are then placed n position and thereafter, as above described, effectually prevent accidental displacement of the sleeve. rlhe operator is then seated with the feet upon the lugs 12 13 and the hands grasping the handles 30 31, when the churning operation may be very easily accomplished, as will be obvious. The motion of the dasher may be in either direction or a forward-and-back motion, as may be preferred or the condition of the cream may require. After the churning is completed the cover members are removed, the sleeve 34 depressed to release the dasher-shaft, and the latter removed. The stop-pawl 21 and .hook 17 are then released and the frame'lS tilted over to release the hook 19 from the loop 16 and the frame and its attached gearing removed to leave the receptacle entirely free from all obstructions to the removal of the butter and buttermilk and to permit the ready cleansing of all the parts.

The device is simple in construction, convenient to use, and easy of operation and can be inexpensively manufactured.

Having thus described the invention, what is claimed is- In a churn, a cream-receptacle, a dasher-staff stepped for rotation therein, a two-part cover having recesses cooperating to form abearing for the staff, a frame supported upon the cream-receptacle, a vertically-disposed driven shaft supported in said frame and terminating in a non-circular portion at its lower end, a sleeve having a limited sliding movement upon the upper end'of the dasher-staff, and terminating in a contracted socket adapted to engage the non-circular portion of the driven shaft, and a spring in the sleeve interposed between the contracted portion or socket and the upper extremity of thedasher-staff.

In testimony that I claim the foregoing as my own I have hereto afxed my signature in the presence of two witnesses.
